Abstract
Description
Technical Field
[0001] The utility model relates to the field of liquid transportation, in particular to a liquid transportation system with a buffer device. Background Art
[0002] For on-line analysis of the components of electroplating solution by XRF detection, the liquid in the electroplating tank needs to be pumped into the detection cavity and then tested. Generally, there is only one inlet and one outlet, and the inside of the cavity needs to withstand the pressure during the transportation by the pump. Therefore, the cover plate (or membrane) used to seal the detection cavity cannot be too thin, otherwise it will be deformed and affect the test accuracy. However, if it is too thick, the fluorescence generated by X-rays is difficult to return. Content of the Utility Model
[0003] The problem to be solved by the utility model is to provide a liquid transportation system with a buffer device to eliminate the influence of the pressure during the liquid transportation by the pump on the detection cavity, so that a thinner cover plate (or membrane) can be used to seal the detection cavity and improve the detection accuracy.
[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a liquid transportation system with a buffer device, including a first buffer bin, a detection bin and a second buffer bin; an inlet for connecting with external equipment is arranged on the first buffer bin, and an outlet is arranged on the second buffer bin; a first connecting pipe is arranged between the first buffer bin and the detection bin, the input end of the first connecting pipe is connected with the first buffer bin, and the output end of the first connecting pipe is connected with the detection bin; a second connecting pipe is arranged between the second buffer bin and the detection bin, the input end of the second connecting pipe is connected with the detection bin, and the output end of the second connecting pipe is connected with the second buffer bin; the detection bin is arranged below the first buffer bin, the input end of the first connecting pipe is arranged at the bottom of the first buffer bin, and the position of the output end of the second connecting pipe is higher than the position of the output end of the first connecting pipe; both the first buffer bin and the second buffer bin are communicated with the external atmosphere. The working principle of the utility model: the electroplating solution to be detected enters the first buffer bin through the inlet, and then under the action of gravity, the electroplating solution to be detected enters the detection bin through the first connecting pipe. To avoid excessive electroplating solution in the detection bin from squeezing the cover plate or membrane, the excess electroplating solution enters the second buffer bin through the second connecting pipe and is discharged through the outlet under the action of gravity.
[0005] As an improvement, a pressure relief port communicated with the external atmosphere is arranged on the second buffer bin, and a third connecting pipe is arranged between the first buffer bin and the second buffer bin.
[0006] As an improvement, one end of the third connecting pipe is arranged at the top of the first buffer bin, and the other end of the third connecting pipe is arranged at the top of the second buffer bin; the pressure relief port is arranged at the top of the second buffer bin.
[0007] As an improvement, the output end of the first connecting pipe is arranged at the lower part of the side surface of the detection bin; the input end of the second connecting pipe is arranged at the upper part of the side surface of the detection bin, and the output end of the second connecting pipe is arranged at the side surface of the second buffer bin.
[0008] As an improvement, the inlet is arranged at the side surface of the first buffer bin, and the discharge outlet is arranged at the bottom of the second buffer bin.
[0009] The beneficial effects of the utility model are as follows: through the buffering of the electroplating solution by the first detection bin, the electroplating solution flows into the detection bin by gravity, avoiding excessive extrusion of the cover plate or film on the detection bin caused by too high flow rate of the electroplating solution; the redundant electroplating solution is discharged through the second buffer bin to ensure that the cover plate or film on the detection bin will not be excessively extruded due to too much electroplating solution in the detection bin; the utility model eliminates the pressure in the pump transportation process, can apply a thinner cover plate or film in the on-line electroplating solution detection, and further improves the detection accuracy.

Detailed Embodiment
[0012] The present utility model will be further described in detail below with reference to the drawings in the specification.
[0013] As Figure 1As shown in the figure, a liquid transportation system with a buffer device includes a first buffer bin 1, a detection bin 2, and a second buffer bin 3. An inlet 11 is provided on the side of the first buffer bin 1. At the inlet 11, devices such as a pump are used to extract electroplating solution into the first buffer bin 1. The detection bin 2 is arranged below the first buffer bin 1. The top of the first buffer bin 1 is in communication with the outside atmosphere. A first connecting pipe 12 is provided between the detection bin 2 and the first buffer bin 1. The input end of the first connecting pipe 12 is arranged at the bottom of the first buffer bin 1, and the output end of the first connecting pipe 12 is arranged at the lower part of the side of the detection bin 2. After the electroplating solution enters the first buffer bin 1, it enters the detection bin 2 through the first connecting pipe 12 under the action of gravity. A second connecting pipe 21 is provided between the detection bin 2 and the second buffer bin 3. The input end of the second connecting pipe 21 is arranged at the upper part of the side of the detection bin 2, and the output end of the second connecting pipe 21 is arranged at the side of the second buffer bin 3. The electroplating solution enters the detection bin 2 from the lower part of the side of the detection bin 2, and then the liquid level in the detection bin 2 slowly rises. Since the bottom position height of the first buffer bin 1 is higher than the top surface height of the detection bin 2, and the first buffer bin 1 is in communication with the outside atmosphere, the electroplating solution in the detection bin 2 will not flow back to the first buffer bin 1 through the first connecting pipe 12. When the liquid level in the detection bin 2 rises to the position of the input end of the second connecting pipe, it indicates that the electroplating solution in the detection bin 2 is sufficient. To prevent the excess electroplating solution from deforming the cover plate or film on the detection bin 2, the excess electroplating solution enters the second buffer bin 3 through the second connecting pipe 21. A discharge port 32 is provided at the bottom of the second buffer bin 3, and the electroplating solution in the second buffer bin 3 can be discharged under the action of gravity, or the electroplating solution in the second buffer bin 3 can be discharged by connecting a pump to the discharge port 32. Thus, it is ensured that a thinner cover plate or film can be used for the detection bin 2 to seal and detect the electroplating solution in the detection bin 2, improving the detection accuracy.
[0014] A pressure relief port 31 is provided at the top of the second buffer bin 3 and is in communication with the outside atmosphere. A third connecting pipe 13 is provided between the first buffer bin 1 and the second buffer bin 3. The two ends of the third connecting pipe 13 are respectively arranged at the tops of the first buffer bin 1 and the second buffer bin 3, so that the first buffer bin 1 is indirectly in communication with the outside atmosphere. The discharge port 32 is arranged at the bottom of the second buffer bin 3.
[0015] Working principle of the present utility model: The electroplating solution to be detected enters the first buffer bin 1 through the inlet 11. Subsequently, under the action of gravity, the electroplating solution to be detected enters the detection bin 2 through the first connecting pipe 12. To avoid excessive electroplating solution in the detection bin 2 from squeezing the cover plate or the film, the excess electroplating solution enters the second buffer bin 3 through the second connecting pipe 21 and is discharged through the discharge port 32 under the action of gravity or the electroplating solution is discharged by a suction pump. The present utility model eliminates the influence of the pressure generated by the pump during the liquid transportation on the detection bin 2, so that a thinner cover plate or film can be used for the detection bin 2 to perform sealing detection, thereby improving the detection accuracy.
